Bolt Tensioner Using

Bolt tensioner using

Bolt hydraulic stretcher short bolt tension, it uses hydraulic booster pump (ultra high pressure hydraulic pump) source, according to the tensile strength, yield tensile and elongation coefficient determined, using ultra high pressure pump the stretch, the bolt is applied force in the elastic deformation zone is elongated the diameter of the bolt slight deformation, so that the nut is easy to loose, and it can be used as a hydraulic interference connection device of applied axial force, top pressure installation. The biggest advantages of stretcher can make a plurality of bolts and fixed value fastening and disassembly, uniform force distribution, is a safe, efficient and fast tool is the best way to bolt fastening and disassembly of various specifications. Used in petrochemical, nuclear power, wind power, hydropower, thermal power, ships, railways, aerospace, mining, heavy machinery and other fields. According to the different working conditions and user requirements, the design of special drawing device can be done.
